Answer:37.4x
Step-by-step explanation:
Answer:
Option (D)
Step-by-step explanation:
Surface area of a square pyramid is determined from the formula,
Surface area = Area of the square base + 4(Area of one lateral triangular side)
Area of the base = (Side)²
= 8²
= 64 cm²
Area of one lateral triangle = 
= 
= 32 cm²
Therefore, surface area of the square pyramid = 64 + 4(32)
= 64 + 128
= 192 cm²
Therefore, Option (D) will be the correct option.
Let k be the scale factor relating two similar prisms

and

, such that for corresponding parts of prisms

and

(for heights, in particular) we have

. In our case

.
For surfaces area we have

.
So, the right answer is 4:25 (choice B)
Answer:
mean-11
mode-none
range-10
median-12
Step-by-step explanation:
Answer: The correct option is (D) 196608.
Step-by-step explanation: We are given to find the value of the 9th term in the following geometric sequence :
3, 12, 48, 192, . . .
We know that
the n-th term of a geometric sequence with first term a and common ratio r is given by

For the given sequence, we have
first term, a = 3 and the common ratio, r is given by

Therefore, the 9th term of the given sequence will be

Thus, the required 9th term of the given sequence is 196608.
Option (D) is CORRECT.
